DANVILLE — A falling tree is being blamed for the death Monday morning of a woman driving on Interstate 680, the California Highway Patrol said.
Authorities have not given an age or residence for the woman, who died at the scene.
The fatality happened about 8:55 a.m. Monday in the northbound lanes of I-680 north of El Cerro Boulevard. The crash closed three of four freeway lanes; at one point, a Sig alert was issued.

CHP Officer Brandon Correia said the woman was driving a newer model Mercedes by herself when a “very large 50 to 60-foot older tree either falls on top of her vehicle or directly in front of it causing her to crash. It was just a horrible tragedy.”
Correia said he was not aware of any other injuries or damaged vehicles.
The woman had to be extricated from their vehicle and was pronounced dead at the scene.
The CHP said the fallen tree, which had been on a slope alongside the freeway, was also blocking lanes of the freeway and it would be some time before it was removed from the roadway.
Authorities did not give an estimate how long the freeway lanes would be closed.
